1. A method, comprising:
- establishing a discontinuous receive/discontinuous transmit (DRX/DTX) session with a serving cell;
transmitting, from a mobile station, an access probe to one or more non-serving cells during the DRX/DTX session;
receiving, at the mobile station, propagation delay information from at least one of the one or more non-serving cells responsive to the access probe; and
obtaining a position location for the mobile station, the position location being determined based, at least in part, on the propagation delay information.

6. A mobile station comprising:
-
memory; a receiver; a transmitter; and a processor coupled to the receiver, the transmitter and the memory, wherein the processor and memory are configured to; establish a discontinuous receive/discontinuous transmit (DRX/DTX) session with a serving cell; initiate transmission, via the transmitter, of an access probe to one or more non-serving cells during the DRX/DTX session; receive, via the receiver, propagation delay information from at least one of the one or more non-serving cells responsive to the access probe; and obtain a position location for the mobile station, the position location being determined based, at least in part, on the propagation delay information. - View Dependent Claims (7, 8)

9. An apparatus for use in a mobile station, the apparatus comprising:
-
means for establishing a discontinuous receive/discontinuous transmit (DRX/DTX) session with a serving cell; means for transmitting an access probe from the mobile station to one or more non-serving cells during the DRX/DTX session; means for receiving, at the mobile station, propagation delay information from at least one of the one or more non-serving cells responsive to the access probe; and means for obtaining a position location for the mobile station, the position location being determined based, at least in part, on the propagation delay information. - View Dependent Claims (10, 11)

12. An article, comprising:
-
a non-transitory storage medium having stored thereon machine-readable instructions executable by a processing circuit of a mobile station to cause the mobile station to; establish a discontinuous receive/discontinuous transmit (DRX/DTX) session with a serving cell; transmit an access probe to one or more non-serving cells associated with one or more of the received position location pilot signals during the DRX/DTX session; receive propagation delay information from at least one of the one or more non- serving cells responsive to the access probe; and obtain a position location for the mobile station, the position location being determined based, at least in part, on the propagation delay information. - View Dependent Claims (13, 14)
